The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch. To be honest, looking at the next couple of weeks, it’s a bit of a slow burn. There’s no real swell to get excited about for a good long while, and we’ve got a solid gap of nothing but tiny, poor surf conditions ahead. The first sign of anything worth paddling out for doesn’t show up until the morning of Monday the 17th, and even then it’s just "surfable." So, you’re looking at over a week of flat to knee-high slop.
The standout window, the one that’s got my attention, arrives on the morning of Tuesday the 18th at Karramarro. That’s when we finally see some life. The forecast points to a clean 8ft swell from the NW, and with light offshore winds from the WNW making it glassy, this is the pick of the whole period. The combined wave energy is strong at 765, so there’s some proper grunt behind it. This is a point break that works best on a NW swell, and that’s exactly what we’re getting. It’s an advanced wave though, and with 8ft, it’s going to be too much for beginners. Also, this break is inconsistent, so don’t expect a conveyor belt. For the experts out there, this is the session to circle on the calendar.
Before that, the morning of Sunday the 16th sees a bump to 5ft from the WNW, but it’s coming in at a short period and the winds are messy with a cross-shore. It’s enough to get wet, but the quality is poor.
After that Tuesday blast, things settle back down quickly. The rest of the week and into the next fades to small, poor surf again with a mix of onshore and cross-shore winds. There’s a pulse of longer-period swell (11 seconds) on the morning of Friday the 21st with 4ft from the NW, but the wind is a cross-shore and the surf is only rated marginal, so it’s a maybe for the die-hards.
Rusty out.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
